Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Advanced Engineering Materials, EarlyView.We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

A High-Power-Density Converter
IEEE Industrial Electronics Magazine, 2010This article presents the development and experimental performance of a 10-kW high-power-density three-phase ac-dc-ac converter. The converter consists of a Vienna-type rectifier front end and a two-level voltage source inverter (VSΓ)To reduce the switching loss and achieve a high operating junction temperature, the SiC JFET and SiC Schottky diode are ...

Thermoacoustics at high power density
The Journal of the Acoustical Society of America, 1996Some applications of thermoacoustics will require high power density to reduce the cost and size of the hardware needed for a given total power. Such high power density can be reached by using high acoustic amplitudes, but this leads to significant differences between the actual operation and predictions based on the acoustic approximation.

Microthermophotovoltaic power generator with high power density
Applied Thermal Engineering, 2009Abstract A promising energy source for portable MEMS devices, microthermophotovoltaic (micro-TPV) power generator, is described in this paper. The system mainly consists of a micro SiC combustor, and a GaSb photovoltaic (PV) cell array and a simple nine-layer dielectric filter, with a volume of about 3.1 cm 3 .

A high power density VHSIC power supply
Fifth Annual Proceedings on Applied Power Electronics Conference and Exposition, 1990A regulated 3.3 V, 10 A supply that combines several innovative approaches is described. The power stage is based on the Cuk converter which allows a very effective application of the integrated-magnetics technique: all magnetic elements (input and output filtering inductors, transformer) are combined on a single magnetic core resulting in a very ...

SH3: high code density, low power
IEEE Micro, 1995Hitachi's SH series microprocessors feature 32-bit RISC architecture with a 16-bit, fixed-length instruction set. We describe SH3, a pipelined implementation of the SH architecture with on-chip cache, MMU, and software-programmable power management.

High-Power-Density Organic Radical Batteries
Topics in Current Chemistry, 2017Batteries that are based on organic radical compounds possess superior charging times and discharging power capability in comparison to established electrochemical energy-storage technologies. They do not rely on metals and, hence, feature a favorable environmental impact.
